Box-sizing Property
/* Safari */
The Box-sizing property allows you to define specific elements that match a region in a specific way.
For example, if you need to place two boxes with borders side-by, you can set box-sizing to "Border-box". This allows the browser to render a box with the specified width and height, and place the border and padding into the box.
The width and height set for the element determines the bounding box of the element.
That is, any padding and borders specified for the element will be drawn within the set width and height.
The width and height of the content can be obtained by subtracting the border and padding from the set width and height.
